Tailstock sleeve guide for machine tools especially lathes

Abstract

A tailstock sleeve guide for lathes comprising two axially spaced guide sleeves which guide the tailstock sleeve and are inserted into a bore of a housing. Adjustment of the radial guide clearance of the tailstock sleeve is effected by axially compressing the guide sleeves. Between the two guide sleeves (4, 5) a claming means (6) act thereon to minimize the time required for the adjustment of the two guide sleeves to identical guide clearance of the tailstock sleeve.

We claim: 
     
       1. An adjustable sleeve guide for tailstocks of lathes and the like comprising; two axially spaced substantially identical guide sleeves for guiding a tailstock sleeve, a housing having a bore receiving the guide sleeves, a clamping means in the bore between the sleeve guides and comprising a plurality of axially extending screws urging the guides in opposite axial directions, a ring attached to the housing adjacent one end of the bore and securing one guide sleeve against axial movement, said ring and said one guide sleeve being provided with aligned openings providing access to said axially extending screws, and a key selectively drivingly engageable with said screws on entry into the associated access opening.
